We're having a
really strange problem with the openssl crypto library -- it keeps segfaulting
down in SHA1_Update when called from an NSAPI plugin (running in NES 3.6).
I've tried building
the library with optimizations off and all that fun stuff, and have run the test
suite which it passes with flying colors. I've also written various pieces
of test code which drive the crypto lib with both static and dynamic linking,
all works fine. However, every time we run it inside NES, it
crashes.
I've reduced it down
to a simple piece of test code which promptly crashes the web server when
invoked.
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <time.h>
#include <nsapi.h>
#include <stdlib.h>
#include <string.h>
#include <time.h>
#include <nsapi.h>
NSAPI_PUBLIC int openssl_test( pblock *param, Session *sn,
Request *rq )
{
char seed[] = "some arbitrary data to seed the random number generator";
{
char seed[] = "some arbitrary data to seed the random number generator";
printf ( "seeding..." );
RAND_seed( seed, sizeof seed - 1); // Probably don't need the -1, but I'm getting paranoid :)
printf ( "done\n" );
return REQ_PROCEED;
}
RAND_seed( seed, sizeof seed - 1); // Probably don't need the -1, but I'm getting paranoid :)
printf ( "done\n" );
return REQ_PROCEED;
}
To build (assuming
you have openssl and netscape libs in appropriate
places...):
gcc -G -o
test_plugin.so test_plugin.c -lcrypto -lnsl -lsocket -DUNIX -DXP_UNIX
-D_REENTRANT
Add to the server's
obj.conf:
Init
fn="load-modules" funcs="openssl_test"
shlib="wherever_you_put_your_library"
Init
fn="openssl_test"
Interestingly, if I link against the old SSLeay
crypto library it works fine!!!!! (ok...I have an old binary, not quite sure how
it was built...maybe something in the build options...probably not since all the
tests pass fine?).
Any and all help is
greatly appreciated :)
